Application filed December 21, 1914. Serial No. 878,398.

To all whom it may concern:

Be it known that I, RAYMOND L. LOUDER- BACK, a citizen of the United States, residing at Middletown, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Horseshoe- Calks, of which the following is a specification.

This invention contemplates a new and improved horse shoe calk and has as its primary object to provide a device of this character adapted to be readily attached in wet weather or during the winter months when the roads are icy, to the shoe of a draft animal, although, it is to be understood, that the calk may be used under ordinary circumstances, in any instance where it is desired that the draft animal be roughly. shod.

A further object of the invention is to provide a calk which will be adapted for attachment to the conventional type of horse shoe now in common use and which may be applied directly to the shoe upon the foot of a draft animal. l p

The invention has as a still further object to provide a horse shoe calk wherein the act of connecting the calk with the shoe of the animal will cause the calk to seat firmly against the shoe to thus provide a thoroughly rigid structure. And a still further object of the invention is to provide a horse shoe calk wherein the working element employed may be removed from the calk for the purpose of sharpening, or in the event it is desired, after an old working element has become worn out, to substitute a new one.

Other and incidental objects will appear as the description proceeds and in the drawings wherein I have illustrated the preferred embodiment of my invention and wherein similar reference characters designate corresponding parts throughout the several views, Figure 1 is a side elevation showing both the preferred and modified forms of my invention applied, the shoe being partly broken away and shown in section, however, to illustrate the modified form of the invention, Fig. 2 is a horizontal section showing the'calk applied, Fig. 3 is a similar view illustrating the calk adjusted to engage the shoe, Fig. 4; is a bottom plan view of the calk, and Fig. 5 is a perspective view showing the parts of the calk detached from each other and arranged in proper relative position.

Coming now to more particularly describe the invention, it will be seen upon reference to the drawings that my improved horse shoe calk includes a body portion 10 which is preferably formedwith 'a flat inner face as illustrated andwhich at one extremity is provided with a laterally extending flange 11. Formed integrally on the opposite extremity of the body portion are the spaced arms 12, the said arms projecting laterally from the body portion in the same direction withthe flange 11 and being connected with the body portion adjacent the side edges thereof. Preferably, the body portion 10 is tapered longitudinally toward the flange 11 from a. point immediately above the inner extremities of the arms 12, although, such configuration is, of course, purely arbitrary. The arms 12 extend in substantially parallel relation to each other and are cut away upon one side at the inner extremities thereof to provide inclined faces 13 sloping longitudinally of the arms laterally away from the body portion 10, the adjacent upper edges 14: of the arms, at the outer extremities thereof being preferablyflat and smooth.

Disposed :for detachable connection; with the body portion 10 is a calk indicated as a 7 whole at 15in Fig. 5 of the drawings. It will be seen that the body portion 16 of the calk is substantially rectangular and is disposed to be received between the arms 12, the end walls of the body portion being flat to confront the flat inner faces of the arms 12, while the outer extremity thereof is preferably rounded as shown.

Medially formed in the body portion 16, is a longitudinally extending opening, which, adjacent the fiat upper face 17 of the calk is enlarged and provided with inwardly converging walls to form a seat 18. Detachably engaging in said opening and secured therein in any suitable manner is a working element 19 which, at one extremity, is provided with a head 20 fitting within the seat 18 and provided with beveled side walls engaging the converging walls of the said seat, it being observed that when the working element' 19 is operatively connected with the calk,-tl1e flat upper face of the head, 20 is disposed flush with the flat upper face 17 of the body portion 16. At its extremity opposite the head 20, the working element 19 is cut away to provide a working edge 21.

It will be observed that the working element 19 is of such length as to extend well beyond the lower extremity of the body portion 16 of the calk to engage the ground or roadway, and attention is called to the fact that in thus providing a detachable working element, the said element may be readily removed from the body portion of the calk for the purpose of sharpening if desired, or when it becomes worn away in 7 vide the transversely beveled shoulders 23 disposed to seat upon the shoulders 13 of the said arms.

Formed integrally with the body portion 16 and extending laterally from the upper extremity thereof, is an externally screw threaded shank 24 which is arranged medially of the body portion and is disposed to extend longitudinally between the arms 12, it being observed upon reference to Figs. 2 and 4 of the drawings, that the said shank is disposed in a plane with the arms. Detachably fitting upon the shank 24 is an internally screw threaded locking nut 25.

HCoacting with the body portion 10 is a clamping plate 26-which is provided with an opening'27 medially thereof, substantially, disposed to loosely receive the shank 24. Upon its side edges,xand adjacent one extremity. thereof, .the plate 26 is formed with oppositely disposed notches 28, adapted to receive the arms 12, the plate being slidable longitudinally upon the arms. "At opposite extremities, the plate 26 is provided with laterally extending confronting flanges 29 and 30, the flange29 being disposed to bear beneath the shank 24, while the flange 30 is arranged to confront the, flange 11 to coact therewith.

Having thus described the construction of the calk, the manner'in which it is applied will now be explained.

The body portion 10 of the calk is arranged upon theheel of the shoe in the rear of the hoof of the animal as illustrated in Fig. 1 of the drawings with the flat inner face thereof seating against the outer edge of the shoe and with the flange 11 engaging over the upper face thereof, it being observed that the flat upper edges of the arms 12 are thus disposed to rest or seat against the lower face of the shoe. The calk proper is then applied with the'body portion 16 thereof disposed between the arms 12 and with the shoulders 23 seating upon the shoulders 13 in which position, it will be observed that the upper flat face of the body portion 16 confronts the lower face of the shoe, while the shank 24 extends out beneath the hoof of the animal. The clamping plate 26 is then applied in the manner heretofore set forth to bear against the inner edge of the shoe with the flange 13 engaging over the upper face thereof. The locking nut 25 is then adjusted upon the shank 24.

It will be noted upon reference to Fig. 2 of the drawings that when initially applied, the heel of the shoe will be held loosely between the flanges 11 and 30 and the upper face of the body portion 16 of the calk proper, and particular attention is now directed to the manner in which the said calk is brought into binding engagement with the shoe.

The nut 25 is moved inwardly upon the shank 24 to engage the clamping plate 26 which, in turn, will correspondingly move the body portion 16 of the calk longitudinally between the arms 12. It will be seen that as the body portion 16 is thus moved, the shoulders will ride upwardly upon the shoulders 13 toward the flanges 11 and 30 to securely bind the body of the shoe between the calk 15 and the said flanges. Thus, the entire structure may be rigidly secured to the shoe and it will be observed that the action of operatively connecting the calk with the shoe will also cause the calk to rigidly seat thereagainst. Furthermore, attention is called to the fact that the lower face of the shoe will bear over the head 20 of the working element 19 to thus assist in securely maintaining said working element in position within the body portion 16 of the calk.

From the foregoing description, it will, of course, bereadily understood that the calk may be readily applied to the shoe of a draft animal or removed as desired, and for this purpose any suitable type of wrench may be employed.

It is intended, in use, that one of my improved calks shall be connected with the heel of the shoe of the draft animal upon each side thereof so that an even tread will be presented.

In Fig. 1 of the drawings, I have illustrated a slight modification of the invention in the form of a calk particularly adapted to be applied to the toe portion of a shoe. In this form of the invention, the clamping plate 26 is made relatively shorter than as embodied in the preferred form, and the flange 30 is disposed to engage within a suitable notch or slot 33 formed in the inner edge of the shoe. This construction is necessary owing to the presence of the hoof of the animal bearing over the upper face of the shoe, making it impracticable to connect the clamping plate 26 with the shoe at the toe portion thereof, as in the preferred form of the invention. Otherwise, the construction disclosed in this modification is identical with that. found in the preferred embodiment of the invention and a further description thereof, will not, therefore, be given.
